Habitat. — Dredged off Inverary by Dr. Grwyn Jeffreys in July, 1866. One was in a 

 tube in a valve of Pecten. At Station XXXIV ' Porcupine ' Expedition of 1869, in 725 

 fathoms on mud and sand, and a variety in 539 fathoms in grey mud in the Expedition of 

 1870. Off Balta in fifty and ninety-five fathoms. Dredged fifty-five miles west of 

 Valentia, Ireland, in sixty fathoms (J. Gr. Jeffreys). 



Amongst corals and mud, Norway (Canon Norman) ; Adria (Marenzeller) ; forty-five 

 fathoms off Cape Sagres, 'Porcupine,' 1870. Extends to Canada (coll. Dr. Whiteaves). 



Head with five long tentacles, the median being longer than the others, and in spirit 

 presenting an articulation at the tip. 1 The adjoining pair have a tendency to further 

 crenulation at the tip, whilst the external pair, which are considerable shorter, have a 

 still more evident crenulation. In origin the median tentacle is most posterior ; the outer 

 lateral arise in front of the other three. The eyes are of moderate size, black, and lie in 

 a line behind the outer lateral tentacles, and to the exterior of the bases of the inner 

 lateral tentacles. The palpi are fused, leaving, however, a deep notch in front and a deep 

 groove ventrally. The palpi are excavated or pitted superiorly. 



Body 6 — 8 ins. in length, little tapered anteriorly, but gradually diminishing to a 

 slender tail posteriorly, where it terminates in two long caudal cirri beneath the vent. In 

 the preparations it is rounded dorsally, and somewhat flattened ventrally. The first 

 segment is three or four times the breadth of the second, and has a well-marked lateral 

 notch on each side, and its front edge is concave from side to side ventrally. The second 

 segment is even narrower than the succeeding, and carries dorsally the two tentacular cirri, 

 which are slightly crenulate in spirit, and reach fully to the anterior border of the first 

 segment. Like the other processes they are tapered. 



1 Muller's N'. pennata had non-articulate tentacles.
